When using a change-driven approach, the business analyst initially creates a high-level requirements list to provide a preliminary outline of what the initiative aims to achieve. This high-level list is commonly known as 'requirements envisioning,' which serves to set the vision for the future requirements development and gives a basis for more detailed requirements gathering. Project scope and product scope are broader terms that define the overall extent of work and deliverables, not just the initial high-level requirements. 'Requirements foundation' is not a commonly used term for this context.
